Ac Input Alarm Thresholds Configuration Example; Dc Output Alarm Thresholds Configuration - 3Com 8800 Configuration Manual

3Com Switch 8800 Configuration Guide
Note:
You can set the thresholds to any appropriate values in the range, but make sure
the lower threshold is less than the upper threshold.
For 220 VAC input, it is recommended to set the upper threshold to 264 V and the
lower threshold to 181 V.
For 110 VAC input, it is recommended to set the upper threshold to 132 V and the
lower threshold to 90 V.

52.2.2 AC Input Alarm Thresholds Configuration Example

I. Network requirements
Set the overvoltage alarm threshold of AC input for PoE PSUs to 264.0 V.
Set the undervoltage alarm threshold of AC input for PoE PSUs to 181.0 V.
II. Configuration procedure
Enter system view.
<SW8800> system-view
Set the overvoltage alarm threshold of AC input for PoE PSUs to 264.0 V.
[SW8800] poe-power input-thresh upper 264.0
Set the undervoltage alarm threshold of AC input for PoE PSUs to 181.0 V.
[SW8800] poe-power input-thresh lower 181.0
Display the information about the AC input for the PoE PSUs.

52.3 DC Output Alarm Thresholds Configuration

You can set the DC output alarm thresholds for the PoE PSUs to enable the Switch
8800 to monitor the DC output voltages of the PSUs in real time through the PoE
supervision module.
